The initial step in implementing the 4.0mm USS system involves making small incisions on the patient’s back. These incisions are deliberately kept minimal to reduce the impact on the surrounding soft tissues. Once the incisions are created, specialized surgical instruments come into play. These instruments are designed with precision to carefully carve out tunnels within the bone. This process demands a high level of surgical skill as the tunnels need to be accurately positioned and sized to ensure a proper fit for the subsequent components of the system. The creation of these tunnels sets the stage for the insertion of the rod and other implants, all while minimizing trauma to the patient’s body.
Following the formation of the tunnels, a 4.0mm diameter rod is inserted into them. This rod serves as the fundamental structural element, acting as the backbone of the entire spinal construct. It plays a crucial role in providing overall stability to the spine. During normal body movements and activities, the spine is subjected to various forces, such as those from bending, twisting, and weight-bearing. The rod effectively distributes these forces along its length, preventing excessive stress on any particular part of the spine. Its placement within the tunnels is carefully executed to align with the natural curvature and anatomy of the spine, laying the groundwork for the attachment of additional implants.
Once the rod is in position, various implants including screws and hooks are attached to it. These implants are strategically placed to engage with the bony structures of the spine. The screws, for instance, are inserted into the vertebrae with precision, ensuring a firm grip on the bone. Hooks are utilized to interact with different aspects of the spinal anatomy, providing supplementary support. The careful placement of these implants is essential as they work in conjunction with the rod to create a unified and stable system. Surgeons rely on their expertise and knowledge of spinal anatomy to position these components optimally, enhancing the overall stability of the spine and facilitating the correction of any deformities or fractures.
After all the necessary implants are attached to the rod, the next critical step is to tighten them. This tightening process serves two important purposes. Firstly, it compresses the fracture segments, if there are any. By applying controlled compression, the fractured parts of the spine are brought closer together, which is beneficial for promoting bone healing. This compression creates an environment where the body’s natural bone repair mechanisms can work more effectively. Secondly, tightening the implants helps restore the spine’s natural alignment. In cases where the spine has been misaligned due to fractures, deformities, or other issues, this step corrects those irregularities, ensuring that the spine is positioned in a way that is anatomically correct and conducive to proper function and healing.
Over time, a remarkable biological process occurs around the implants. The bone tissue adjacent to the implants gradually heals and grows, eventually creating a solid fusion. This fusion further stabilizes the spine by integrating the affected vertebrae into a single, unified structure. It marks the successful culmination of the surgical intervention as the spine becomes stronger and more resilient. With this solid fusion in place, patients can expect improved spinal function, reduced pain, and a better quality of life as they regain the ability to move and perform daily activities with greater ease and stability.
